Abstract:

Objective We retrospectively evaluated the clinical and radiological outcomes of posterior lumbar interbody fusion (PLIF) using a unilateral single cage and a local morselized bone graft. Methods Fifty five patients who underwent PLIF with a unilateral single cage filled with local morselized bone graft were enrolled in this study. The average follow-up duration was 39.2 months. The clinical outcomes were evaluated with the visual analogue scale (VAS) at the pre-operative period, at 1 year post-operation and at the final follow-up, the Oswestry Disability Index and the Prolo scale at the final follow-up; the radiological outcomes were evaluated according to the change of bone bridging, the radiolucency, the instability and the disc height. Results For the clinical evaluation, the VAS pain index, the Oswestry Disability Index and the Prolo scale showed excellent outcomes. For the radiological evaluation, 55 cases showed complete bone union at the final follow-up. Conclusion PLIF using a unilateral single cage filled with a local morselized bone graft for treating degenerative lumbar spine disease provides excellent outcomes according to the clinical and radiological evaluation.
